mkudffs - create an UDF filesystem
SYNOPSIS
mkudffs [ switches ] device [ blocks-count ]
DESCRIPTION
mkudffs is used to create a UDF filesystem on a device (usually a disk). device is the special file corresponding to the device (e.g
/dev/hdX). blocks-count is the number of blocks on the device. If omitted, mkudffs automagically figures the file system size.
OPTIONS --help Display the usage and list of options.
-b,--blocksize= block-size
Specify the size of blocks in bytes. Valid block size vales are 1024, 2048 and 4096 bytes per block. If omitted, mkudffs block-size
is 2048.
-r,--udfrev= udf-revision
Specify the udf revision to use. Valid revisions are 0x0201, 0x0200, 0x0150, and 0x0102. If omitted, mkudffs udf-revision is 0x0201.
--lvid= logical-volume-ident
Specify the logical volume identifier.
--vid= volume-ident
Specify the volume identifier.
--vsid= volume-set-ident
Specify the volume set identifier.
--fsid= file-set-ident
Specify the file set identifier.
--strategy= strategy
Specify the allocation strategy to use. Valid strategies are 4 and 4096. If omitted, mkudffs strategy is based on the media-type.
--spartable= spartable-number
Specify the number of sparing tables to write to disc. Valid numbers are 1 - 4. This option implies --media-type=cdrw.
--media-type= media-type
Specify the media type. Valid media types are:
hd hard drive
dvd DVD (Digital Versatile Disc)
dvdram DVD-RAM (Digital Versatile Disc-Random Access Memory)
worm WORM (Write Once Ready Many)
mo MO (Magneto Optical)
cdrw CD-RW (CD Read-Write)
--space= space
freedbitmap Freed bitmap
freedtable Freed table
unallocbitmap Unallocated bitmap
unalloctable Unallocated table
--ad= ad
inicb Allocation Descriptors in ICB
short Short Allocation Descriptors
long Long Allocation Descriptors
--noefe
Don't Use Extended File Entries
--u8 Use 8-bit unicode for file names
--u16 Use 16-bit unicode for file names
--utf8 Use UTF-8 for file names
EXIT STATUS
mkudffs returns 0 if successful, non-zero if there are problems.

MOUNT_UDF(8) BSD System Manager's Manual MOUNT_UDF(8)NAME
mount_udf -- mount a UDF filesystem
SYNOPSIS
mount_udf [-o options] [-s sessionStart] [-n lastRecordedLBA] [-b blockSize] [-p packetSizeInBlocks] [-v verificationPolicy] [-w] devicePath
mountPath
DESCRIPTION
The mount_udf command attaches the UDF filesystem residing on the device devicePath to the global filesystem namespace at the location indi-
cated by mountPath. This command is normally executed by mount(8) at boot time.
The options are as follows:
-o options
Options are specified with a -o flag followed by a comma separated string of options. See the mount(8) man page for possible options
and their meanings.
-v verificationPolicy
This is an advanced option not useful for regular use. It controlls the verification policy when writing to RW type optical media.
Its value can be "meta", "all", or "none". Policy "meta" means only the metadata are verified after they are written. This is the
default policy. Policy "all" means to verify data written, which could be several times slower than policy "meta". Policy "none"
does not verify any data. It is only slightly faster than "meta" in normal cases, but may result a corrupted UDF disc if the write
of metadata fails.
-s sessionStart
This is an advanced option not useful for regular use. When manually mounting a UDF volume with Virtual Partition, it specifies the
start Logical Block Address of the last session where UDF data structures (VRS and AVDP) resides. This value overrides the value
obtained from the device.
-n lastRecordedLBA
This is an advanced option not useful for regular use. When manually mounting a UDF volume with Virtual Partition, it specifies the
last recorded Logical Block Address where the UDF VAT ICB will be searched. This value overrides the value obtained from the device.
-b blockSize
This is an advanced option not useful for regular use. It specifies the block size in bytes used when mounting the UDF volume. This
value overrides the value obtained from the device.
-p packetSizeInBlocks
This is an advanced option not useful for regular use. It specifies the packet size in blocks when manually mounting the UDF volume.
This value overrides the value obtained from the device.
-w This is an advanced option not useful for regular use. It forces to enable the experimental packet writing function on optical media
that has not been fully supported, such as CD-R, CD-RW, DVD-R, DVD+R, HD DVD-R, and BD-R. Writing to these media does not work on
some drives and may cause data corruption or data loss on some other drives. Therefore, this flag should be used only by file system
developers when debugging the experimental write functions.
The -s, -n, -b, and -p flags are not useful in normal use. They are mainly used for debugging and data recovery. Since the -s, -n, and -p
flags are all specified in units of block size, when any of these flags are specified, it is strongly recommended that the -b flag is also
specified.
SEE ALSO mount(2), unmount(2), fstab(5), mount(8)BUGS
Reading of all UDF revisions (1.02 - 2.60) on both block device (e.g., hard drives and USB drives) and most optical media is supported.
Writing to block devices, DVD-RW and DVD+RW is supported with the following exceptions: (1) Cannot write Finder Info, Resource Fork, or other
extended attributes in UDF volumes of revision 1.02 and 1.50; (2) Cannot write to mirrored metadata partition.
HISTORY
The mount_udf utility first appeared in Mac OS X.
